Majority owners: The Mara family -- the 11 children of Wellington and Ann Mara -- own 50 percent of the New York Giants.

The oldest and most prominent of the 11 Mara children is John Mara, 60, who serves as the team's president and chief executive officer. The Tisch family owns the other 50 percent of the team.

Owns stadium (how much invested): Giants ownership co-owns MetLife Stadium with Jets ownership (the stadium cost $1.6 billion to build and was privately financed).

Ownership philosophy: Mara runs the day-to-day operations of the team, but general manager Jerry Reese has control of football operations. Mara is at practices and in meetings but prefers to let his football people run the team and therefore rarely comments publicly during the season on team matters. Tisch is involved in high-level decisions, but in part due to geography is not very involved day to day.
